Wow... this commit should have been a long time ago. Ok. Finished the settings view and controller. Integrated NSUserdefault for persistance of settings, both the settings controller and all controllers that depend on these settings access/store these settings. Finished the UI for the PowerRelay finally. iOS error where the whole view gets displaced by exactly the height of the navigation bar persisted regardless of my best efforts. Really random error. Will post about it on SO. Anyway, found work arodund that allows the UI to work smoothly. Updated the LeDiscovert manager to use the persisted settings as well. Tested that all settings do get persisted. All good.
